Abstract (en)
An apparatus for conveying successively two fluid mediums, especially two drugs, to a human or to an animal client comprising a cylinder 12 with a first piston 9 near to the mouth 1 and a second piston 10 near to the end-plate 13, thus defining three partitions within the cylinder: => partition one is situated between mouth 1 and piston 9 and contains the first medium, => partition two is situated between piston 9 and piston 10 and contains the second medium, => partition three is situated between piston 10 and endplate 13 and takes up the driving gas that is generated by an electrolytic process from gas cells. Piston 9 contains a by-pass 51 and a valve 52 within by-pass 51 for the flow of the second medium through piston 9. <IMAGE>
